Hello experts,
I have a dataset (in x and y format) and I want to fit it using four-parameter Weibull curve. Moreover, I have to find a location where the gradient reaches a value of 0.5 moving from the mid-point of the curve. I really appreciate your valuable inputs and thanks in advance. My data structure is as follow:
X Y
0 47.549
2 46.7
4 47.449
6 49.905
8 53.27
10 57.909
12 62.872
14 67.295
16 70.777
18 72.665
20 73.519
22 73.946
24 74.16
26 74.504
28 75.058
30 75.567
32 75.792
34 75.687
36 75.823
